Last updated at Posted at 2017-12-07

CWL User Guide 8: Additional Arguments and Parameters

Common Workflow Language User Guide: Additional Arguments and Parameters

今回は実行環境の情報が提供されるパラメータruntimeや、argumentsに関する説明があります。

Javaのソースコードをコンパイルしますが、コンパイルには、dockerコンテナを使うので、Javaをインストールする必要はありません。

この回にでてくる主なキーワード

  • arguments
  • runtime

CWLファイル、arguments.cwl

#!/usr/bin/env cwl-runner

cwlVersion: v1.0
class: CommandLineTool
label: Example trivial wrapper for Java 7 compiler
hints:
  DockerRequirement:
    dockerPull: java:7-jdk
baseCommand: javac
arguments: ["-d", $(runtime.outdir)]
inputs:
  src:
    type: File
    inputBinding:
      position: 1
outputs:
  classfile:
    type: File
    outputBinding:
      glob: "*.class"

パラメータファイル arguments-job.yml

src:
  class: File
  path: Hello.java

必要なファイル

簡単な Java のソースコードがかかれたファイルを作成する

echo "public class Hello {}" > Hello.java

実行

実行前確認

Hello.class が存在していないことを確認する
Hello.class が存在すれば、それを削除しておく。

$ rm Hello.class
$ ls Hello.class
ls: cannot access 'Hello.class': No such file or directory

実行方法

cwltool arguments.cwl arguments-job.yml

実行結果

$ cwltool arguments.cwl arguments-job.yml
